IMPROVEMENT IN PUMPS.

The Schedule referred to in these Letters Patent and making part of theum.

To alll rwho/m. it may conce/rn Be it known that I, DANIEL S. EVANS, o'fBrockway, St. Clair county, State of Michigan, have invented a new anduseful Combined Double-Acting Suction and Force-Pump; and I do herebydeclare that the follow-` ing is a full, clear, and vexact descriptionof the construction and operation of the same, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, the same making a part of this specification, 'in which Figurel is a perspective view;

Figure 2, a longitudinal elevation; in whieh A is a handle oribrake.

L L are two cylinders, in which the pistons C C are fitted.

B B, piston or connecting-rods, connecting handles with combinedplungers and suction-boxes, marked C C.

D D, check-valves at lower end of cylinder.

E, holding-valve at the head of the foot-piece or pipe marked F. K

GG, ports, through which the water is 'forced from cylinder topump-head, through valves H H, at head of ports.

I, spout or hose-connection.

The stroke of the pump may be changedby changing connecting-rods inholes 1, 2, 3 in handle.

By disconnecting one connecting-rod, the pump may be operated atone-half its capacity with less power.

This pump may be constructed of wood or of metal, may be operated byhand or steam-power, and is particularly calculated for raising water togreat height or .from Very deep wells.

This pump is claimed to raise or throw water with about one-half thepower used in operating any other pump of the same capacity. s

What I claim as new, and desire to secure by Letters Patent, is-

The two 'cylinders L L, together with the valves D D and valve E, inconnection with vulves H H, the whole constructed substantially as abovedescribed.

Witnesses: DANIEL S. EVANS.
